It has also been reported that the onset begins later during childhood. It causes brain, spinal cord, and optic nerves degeneration and clinically is characterized by acquired motor skills, muscle weakness and hypotonia, lactic acidosis associated with respiratory and kidney dysfunctions. The association with hypertrophic cardiomyopathy has been reported and represents a major anesthesia consideration. Although malignant hyperthermia (MH) has not been reported with Leigh disease, it may be wise to avoid triggering agents as other myopathic conditions with a propensity for MH have been misdiagnosed in the past in the presence of muscular disorders.
